To all whom it may concern."

Be it known that i, "vViLtL-nu I. \Vnrrn, a citizen of the United States, residing at Greenwood, in the county of Johnson and State of .lndiana, have invented certain new and useful improvements in (:an-(ap-llucing Machines, oi' 'which the t'ollowing is a speciliration. i

The object of my invention is to provide a mechanism for automatically placing caps upon (inns which have been previously filled with material to be presei 'ed.

The aecom pan ying draw invention embodied'in an attachment to be placed. over the lending carrier oi a cana-a-pi p1ng"1nachine.

'which the caps are t:

Figure 1 a plan; Fig. 2, a side elevation; Fig. 25, av vertical section or the feeding mcchanism about full size; Fig. 4, a sectiorml detail oftparts of Fig. 3 showing the positions of parts at the timev when a cap is being dis charged from the feed chute; Fig. :3, a similar view showing the positions assumed by the parts at completion of the discharge stroke; .l ig. t), a siniilar View sl'iowing the discharged rap l'alling to final position upon a can," and Figs. 7, and 9 views similar to Figs. i, 5 and (3 respectively, showing another form olcap and ejecting phmger.

.ln thedrawings ltl imlierites a suitable supporting t z'ame haying a plate or table I l in .which is Formed an opening 12 through i be discharged in surcessioniu'iou runs l2; carried beneath plate ll by means ol' a suit ablecarrier "t t. Arranged upon plate ll. between suitable guides 15, is

To this a recipromiing plunger it) provided at its forward end with a portion l" adapted to ngage the caps is. in the present l'orm l show the portion [7 as reduced and rounded to enter The cupped underside ol' the cap 18.

plunger may be given any other suitable form for engagement with the e: ps without departing dirom my invention. Plunger it; is normally held, by means of a spring I), with its end 17 in position to receive a rap in. For the purpose of reciprocating plunger till journal, in l'rame it) upon.

each side oi the earrier it. a shalt 2t) whielu; at. its upper end, is provided with an arm 21 adapted to engage a pin 22 carried by the plunger lo. Secured to each shalt 2t), at a point over the carrier 14, is an arm 23 said arms projecting toward each other in position to be engaged by can l3 as it is carried beneath the plate 11. and separated so as to ings illustrate my rock shafts 2t) and, through arms '2 project, the plunger 16 toward the opening 12. Arranged abox 'e plate It is a guide in which is mounted a vertically reeiprecablc guard 31 which. in the present case; is shown as tubular in form, the internal diameter being slightly greater than the diameter of the caps lo. the top of the plunger 16, either by its own weight or by reason (ii a suitable spring 32.

vLeading to thoguideway formed by guard 31 is a chute 33 in which may be placed a stack. of caps 18 said stack resting upon plunger to. The caps 18 are cupped and theret'ore nest one upon the other so that ordinary ejecting moans cannot be used to The guard 31 nornntlly lies upon eject the. lowermost cap and it is for this puri 'lable l l and eonsemicntly the lower edge of the guard is nearer the table than the top of the tirstv or lowermost cap 18. As a can is carried by warrior 14 between the arms 23 the plunger 16 is projected (as shown in Fig. 4-} forward beneath the gin: rd 2%] toward opening it and said guard yields vertically to permit the passage of the lowermost cap l8 but at all times remaining near enough to the tablc'll to prevent any ejecting movement of the next higher cap, as clearly shown in Fig. 4. (ontinued movement of plunger to "carries the ejected cap to the position shown in Fig. 5 where it lies partially over the opening 12 in table 11. As the can 13 proceeds beneath plate ill it lirst passes through between arms 23 so that spring 19 may return the plunger quickly to its initial position. The can then comes between the arms ol star wheels -10 (only one ol' which is shown) carried by shafts "it jouri'ia cd in frame It) upon opposite s i'les ot' carrier 14 and this movement ol the can causes a rota-- tion of the straits it and a consequent movement. ol' ilH' star wheels -12 (which are similar to the star wheels l0 and similarly placed), iarried by the upper ends oi shafts 4i and lying innnialiately above table 11, and these star wheels 12 engage the eject-ed cap 18 and carry it forward until it dro s through opening 12. In the meantime t e can 13 has advanced sufficiently to lie beneath the opening 12 in position to receive the cap as it;

falls through the opening as shown in Fig. 6. In Figs. 7, 8 and 9 I show a modification which may be used to advantage with some terms of caps. In this form the forward end ol the plunger 16 is cupped to fit the external circumference of the cap 18 and is slightly tapered vertically so as to pass beneaththe bottom of the next higher cap.

it will, of course, be understood that instead of projecting the ejected cap 18 through the hole 12, any other suitable means may be provided Without departing from my invention. A spring finger is projected over opening 12 so as to insure the passage of the caps through the opening.

I claim as my invention:

1. The cpmbination, with a feeding table, of a cap-holding tube. arranged over the table and movable toward and from the table, a cap ejecting member adapted to engage the interior of the initial cap, and means for driving the ejecting member beneath the said tube. i

The combination, with a feeding table, of a cap-holding tubelarranged over the table and movable toward and from the table, a cap-ejecting plunger, means for carrying cans sueeessively'beneath the table, means operated'by the cans for operating the plunger, and means operated by the cans for depositm e ected caps upon the cans.

3. 'i e combination, with a feeding. table, of means for carrying cans in succession beneath said table, a ca -holding tube arranged above the table an movable toward and from the table, a plunger mounted on the table and adapted to be projected beneath said tube, a portion. of said plunger lying initially beneath the tube and adapted to enter the cupped under-side of the lowermost "5- cap, means operated by the cans for. reciprocating said plunger, and means operated by the cans for shoving the-ejected caps from lintahle and depositing them upon the cans.

-i The combination, with a feeding table,

ments of the stac of means for carrying cans in succession be -50 ate b the cans for shoving the ejected capsv from t e table and depositing them upon the cans. i

5. .The combination, with means for hold ing-a series of nested cupped elements in av stack, which means comprises a guard yieldingly movable axially of the stack and engaging two or more of the cupped elements thereof, of ejecting means movable transversely of the line of movement of said yielding guard and adapted to engage the interior of the initial element of the stack and project the same beneath the guard.

6. The combination, with means for holding a series of can caps in an, axial stack, means for ejectin said caps successively therefrom, a guard forming a part of the stack forming means and arranged to cooperate with said ejectin means and yieldable in the line of thicl rnes's of the caps, means for feeding cans in succession to capreceiving position, and means 0 erated by the cans for depositing the ejecte capsupon to project the same transversely of the stack,

and means for on aging the remaining eleand holding the same against transverse displacement.

In witness whereof, I, have hereunto set my hand and seal at Indianapolis, Indiana, this 31st da of July, A. D. one thousand nine hundre and six.

WILLIAM 1 WHITE.
